Each BB is a perfect sphere with no air bubbles and made of 100% natural ingredients.

Shelf Life: There is no concern, just store the bbs in a cool, dry place. H20 alone will not start the degradation of the BBB Bio or BBBMAX Bio bb. The BBB Bio & BBBMAX Bio bbs environmental degradation time is irectly related to numerous environmental factors.
